@MarshLover what's your panel tilt angle? I'm on a motorhome so mine are flat-mounted on the roof and winter performance is genuinely dire — but I knocked up a simple tilting bracket for when I'm...

Hey @SomersetVanLifer, interesting setup! One thing worth flagging - if your Ohme and the commando socket are sharing the same circuit, you'll want to make sure they can't draw simultaneously,...

JackieCrane | ⚓ Narrowboat & Off-Grid Enthusiast | Posts: 847 @Jess1989 @FellGraham is spot on about the voltage drop, but worth adding — the Victron SmartSolar has a nifty fix for this built...

Picked up a 200A shunt monitor off Amazon a few weeks back (one of those Aliexpress rebrands, about £12) to keep an eye on my 100Ah LiFePO4 leisure battery in the van.

DODNerd | 847 posts @RobWebb59 Worth checking your Daly's low-temperature protection settings in the app — the default cutoff from the factory is often set quite conservatively, sometimes as high...

Gibbo39 | Posts: 312 @Del58 your post got cut off mate so we're all guessing a bit, but I'd echo what @SparkySailor is getting at — if you've fitted a DC-DC charger (Victron B2B I'm assuming...

@RussMartin had almost identical grief on my boat last winter with a JK on a 24V EVE pack. Worth checking your cell voltage differential under load.

Hey @PanelChris, nice build! I've got a similar setup — Cerbo GX with a Renogy inverter that obviously won't talk to it directly.

Been scratching my head over this one for a few weeks now. My MultiPlus-II 48/3000 is cutting absorption short and jumping to float when the battery is clearly nowhere near full.

Great write-up @CoastalBoater! One thing worth mentioning that nobody's touched on yet — keep an eye on your alternator charging setup.

Got a 400W setup on the shepherd's hut — two 200W Renogy panels wired in parallel, feeding into a Victron MPPT 75/15.

Really useful thread this. One thing I'd add that nobody's mentioned yet — LiFePO4 cells don't just lose capacity in the cold, they also raise their internal resistance, which can make your BMS...

Fitted a Victron Orion-Tr Smart 30A DC-DC charger to my Transit-based van build about six months ago and it's been brilliant for keeping the leisure bank topped up on the move.

Amy2000 | 156 posts @BorderNomad One thing nobody's mentioned yet — check whether your controller is actually using the correct battery type setting.

@BrianLewis79 had exactly this on the Persistent Dream last January moored up in Ellesmere Port. Brutal cold snap, and my SmartSolar was reading nearly 0.4V higher than what my BMV-712 was showing...

RayCross | 847 posts @OhmsLaw7 Classic one this! Half a volt discrepancy almost always points to voltage drop across your wiring between the two measurement points.

Been running my garden office on a standalone solar setup for about eight months now and trying to work out whether I've got the balance right.

Picked up a pair of APC Smart-UPS 1500s from a local IT recycler for £40 the lot. Swapped the internal sealed lead-acid batteries out for some decent AGM replacements and they've been running...
